Three of Dolly Parton's most beloved albums from the 1970s will be reissued April 3 via RCA Nashville/Legacy. 1971's "Coat of Many Colors," 1973's "My Tennessee Mountain Home" and the following year's "Jolene" all feature previously unreleased studio tracks as bonuses.

"Coat of Many Colors" was Parton's artistic, if not commercial, breakthrough as a solo artist, following more than a dozen albums as Porter Wagoner's duet partner. It spawned three top 20 hits on Billboard's country chart: the title track (No. 4), "My Blue Tears" (No. 17) and "Traveling Man" (No. 20).

An acoustic demo of "My Blue Tears" is among four previously unreleased tracks, as well as the Parton originals "My Heart Started Breaking" and "Just As Good As Gone" and Wagoner's "The Tender Touch of Love."

"My Tennessee Mountain Home," the title cut of which hit No. 15 on the country chart, found Parton channeling her struggles with trying to make it big in Nashville on her own terms. The album is expanded here with "Sacred Memories," which was first released on the 1975 set "Love Is Like a Buterfly."

Parton hit a creative peak with "Jolene," the title song of which has become the most instantly recognizable of her career. "Jolene" and "I Will Always Love You" (later a No. 1 hit for 14 weeks for Whitney Houston in 1992) both topped the country chart. The expanded edition includes four previously unreleased Parton originals: "Cracker Jack," "Another Woman's Man," "Barbara on Your Mind" and "Last Night's Lovin'."

Parton is gearing up for a month-long European tour, which kicks off March 6 in Horsens, Denmark. A North American run is expected later in the year.
